We used one of those on the last firing of a new kiln. Don't buy it unless
you get an agreement to return it for a full refund. Ours never settled down
and gave us no usable readings. We use Fluke brand and love it. More
expensive but it works! Tracy

James,
The arches I have seen laid up with mortar have all had cracks in them.
Keep in mind that we're talking about a small sample size, here! Mark Ward
clearly is an expert in these matters. Anyway, I think the best way (outside
an MFT, of course!) is to lay it up dry just like the walls. If you stagger
the joints on each course by cutting half bricks, the whole arch will lock
together nicely. On the other hand, laying the arch up in 'rings' makes it
easy to replace a single brick later on. Hmmm.
